Well, the easiest solution would be to remove those misbehaving distributions
from the cheeseshop.
However, I think we kid ourselves if we think that the cheeseshop will always
provide a stable set by default. This would be like saying that all packages
from all versions of one Linux distribution are in one repository and nothing
will break.
It'd work if setuptools supported a 'give me a version that works'
feature. You'd just have to specify the working dependencies along with
the loose dependencies in setup.py.
You'd still have potential problems if you use multiple packages that
share a dependency, and the working version they suggest conflicts. It's
then up to the end user to break the conflict. Theoretically, as long as
you'd follow the loose dependencies and we maintain those well, things
would still work.
I can even think of a trivial example. Let's say package A works only with
Python 2.x and package B works only with Python 3.0a. The supported Python
versions are not part of the meta-data of a package. As a naive user, I want
to use both, but can't.
Heh, Python 3 will cause way more problems than this. We should avoid
releasing Python 3 versions for our packages for that reason. If you
release them, I'd suggest picking a different name for the egg
altogether - that's what is typically done in Linux distributions if
there are multiple incompatible versions of a library (GTK 1 and 2, for
instance).
